Tsz Wo Nicholas Sze commented on HDFS-7859:
-------------------------------------------

> ... The overall design and discussion are in HDFS-7337, would you take a look at it.
...

Yes, I looked at it earlier but it did not answer my questions.  Since HDFS-7337 is already
under HDFS-8031, let's move all the related works to HDFS-8031.

> In meetup discussion with [~zhz] and [~jingzhao], it's suggested that we persist EC schemas
in NameNode centrally and reliably, so that EC zones can reference them by name efficiently.
